Not a stats book (although it include some stats), it’s more about how to operationalize goals and objectives into something that can actually be measured, which is probably the most important aspect of any goal that you want to track.

In the (unlikely) event the previous book doesn’t explain the statistics you’re using well enough, this provides additional details. I have the 3rd and 4th editions, which vary only slightly. Not sure what sets the current (6th) edition apart from the earlier versions.
